Closed loop knock sensor?
Never noticed until last night, in closed loop the knock sensor cycles from 0 up to ~2, down to 1 and up to 10 (I have it set set the KS can add or pull 10*, 20 total -10 to +10) over the course of about 5 seconds then repeats.
Actual timing didn't change though.
Just thought that was odd and wondering if it's normal, or does it indicate some type of problem?
OH, you're not playing dumb ...
